This Fluoroelastomer (FKM) rubber hose is found in all submersed Radium fuel systems. It is designed specifically to handle gasoline, alcohol fuels (including E85), and diesel fuel in fully immersed, mobile, stationary, and marine applications. Unlike typical EFI hose, this is engineered for constant contact with liquid petroleum distillates on the inside and outside of this Aramid Fiber reinforced hose. It is excellent for fuel pumps mounted in gas tanks and has great flexibility to work with barbs and hose clamps.
